Thank you for replying. I hadn't considered using the Corona randomizer for simple things like tiles or cubes. Anyway, Mograph, which includes the cloner and all of the effectors with fields etc., is perhaps the most powerful and versatile tool in Cinema. When I picture more sophisticated objects, such as humans for example. When I clone the human, rotate and scale it with the random effector, I will encounter the same issue, and I will be unable to use the Corona randomizer in this case. The person is placed beneath the cloner and assigned its own material tag. Then the cloner completes the cloning process. It signifies that the UV map does not rotate for human clones. The topology and its UVW map are bonded together. As a result, I see no reason why this should be an issue. This problem did not arise with other renderers.
